Liquid crystal polyester resin composition |
(57) A liquid crystal polyester resin composition comprising a liquid crystal polyester
(A) in a continuous phase and a rubber having a functional group reactive with the
liquid crystal polyester (B) in a dispersed phase.
A liquid crystal polyester resin composition of the present invention is excellent
in heat resistance, molding processability and mechanical properties, particularly
in impact resistance and tensile property, capable of improving anisotropy of a molded
article. Furthermore, film formation processability can be improved at a low cost,
and a film produced for the composition has excellent gas barrier property, drawing
property and flexibility.
